-- Information about the crash:
My plasma shell keeps crashing on a regular basis.
Usually when I launch an application, I assume it is the new window that opens
though.
Taskbar and everything disappears for a moment, then it restarts itself. Most
of the time - right now it is gone and I can only use krunner to start things.
It is a reasonably fresh install of Kubuntu and I just upgraded to 25.04, which
did not change any behaviour.
I think the crash reporter already took a stacktrace, here I add the journalctl
logs from 2 of the crashes. But I was not able to see any obvious problem.
